IMPROVEMENT IN DOUBLE-ACTINGl-VALVE CUT-OFFS T0 FLOUR-PACKERS.

Specication forming part of Letters Patent N0. 168,020, dated September21, 1875; application filed March 3o, 1875.

To all whom it may concern:

Beit known that 1,AUGUsTrN M. HoBBs, of Waupaca, Waupaca county, Stateof Wisconsin, have inventeda Double-Acting-Valve,

au gers that before the tubeB can be changedwhich often has to be donein the Eureka Hour-packer many times in a dayit re'- quires two men withheavy iron bars to climb a ladder to the ceiling' before the cut-off Vcan be closed, and which, when closed, leaves ten barrels of flourbetween tube B and cutoff V, which has to be drawn off before the tube Bcan be removed, which takes time, and is universally inconvenient andtroublesome.

ln carrying' out my invention, the doubleacting-valve cut-off, which isat C in Fig. l, being so low down, completely does away with theinconvenience and trouble so much experienced With cut-offs inflour-packers, and especially the cut-off in the Eureka Hourpacker,which is at V in Fig. l. Besides, the double-acting-valve cut-oli' at Oin Fig. 1 is so constructed and applied to flour-packers, and especiallyto the Eureka Hour-packer, that one person standing on the door besidethe tube B can, with one hand, by means of a lever, which is at D inFig. 1, close the cut- 'off at (l, thereby stopping thel flow of ourinto said tube B, and which only leaves, after said cut-ofil at C isclosed, about one half barrel of flour between the tube at B and thecut-off at C, where, as before, in the Eureka flour-packer, it left tenbarrels between the tube B and the cut-off at V, as in Fig. l,

- thereby completely overcoming the inconvenience and trouble so muchexperienced by using the cut-off at V in the Eureka flourpacker.

The valves of my cut-off, which are E and F, are so constructed thatthey are entirely independent of each other, so that when the lever D isin a horizontal position, as represented in Fig. 2, the lower valve E isopened, while the upper valve F remains entirely closed, therebyregulating the ow of our into the tube B, to suit the convenience of theoperator of the machine. Besides, when the lower valve is open thepressure on the upper valve F is so diminished that it can be openedwithout difficulty, and when the valves are both opened they areperpendicular, as shown in Figs. l and 3, and in no Way impede theprogress of the our into tube B, as represented in Fig. l.

lt is evident that the cut-off may be provided With a lever at each endfor operating` Y the sam e.

In closing my cut-o the upper valve F a manner makes my cut-oli' and theother rods much stronger and more durable, which makes my machine farpreferable to any now in use, the valves working independently, beingsilnple of construction, durable., easily worked, and not liable to getout of order.

I claim as my invention- Tube C, having independent valves E, and ifsecured to shafts provided with cogged segments separately engaging withand operated by lever D, as and for the purpose specifled.
